ICE-MARKER.

SPE(IIIFICA'IIONl forming part of Letters Patent No. 624,162, dated May'2, 1 899.

Application filed January 28, 1898 Serial No. 668,286. (No model.)

To all whom t may concern:

Be it known that I, HENRY BoDENsTEIN, a citizen of the United States,residing at Staatsburg, in the county of Dutchess and State of NewYork,have invented certain new and useful Improvements in Ice-Markers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in ice-markers, and has specialreference to an improved insertible tooth and means for adjustablysecuring the same in any desired position.

The main object of my invention is the provision of means for securingan insertible tooth in the frame of an ice-marker at the desired heightor depth to regulate the cut in the ice, and with my improved fasteningthe teeth can be kept in line without filing all the other teeth.

Another object of my invention is theprovision of an insertible ytoothand securing means therefor which may be adjusted in a short time withany ordinary wrench to cut deep or shallow to accommodate the amount ofdraft or the state of the ice; also, that each of the teeth will cut thesame depth with less draft; also, if a tooth should be broken while atwork another can be put in its place in a very short time, and in casethe teeth should become out of line the set-screws below bearing-rollercan be so adjusted as to put the same in proper adjustment, and thus itwill be seen that I provide a useful and practical device which isextremely simple, durable, and inexpensive.

To attain the desired objects, my invention consists of an ice-markerembodying novel features of construction and combination of parts,substantially as disclosed herein.

'ing means connected thereto. Said frame consists of the metal sidepieces 2, which are held together by means of bolts passing through theforward and rear ends of the frame. Adapted to fit in between these sidepieces-in the space are the heel-plates 3,having bolted thereto the sideplates or bushings 3', which form an abutment for the inner ends of theset-screws l2, which pass through the side pieces to hold theheel-plates in alinement, and in case the plates should move to one sideof the frame the set-screws on one side are then loosened, while theones upon the other side are tightened, thus forcing the heels in theirproper alinement. Fitting in the grooves l0, formed near the top of theside pieces upon their inner sides, are the stop-plates l0, which are soplaced in the frame as to leave a space or opening ll for the insertonof the cutting-tooth 6, whose groove or channel 5, formed in its rearface, fits over the tapered forward edge 4 of the heel-plates. To holdthese teeth in their proper place and adjust their points 7 'so thatthey will only cut a certain depth, I form a screw-threaded openinginthe stop-plates 10,

in which is inserted the set-screw 9, whose lower end is adapted tocontact the bearingroller 8, resting in the space or socket formedbetween the front edge of the teeth and the rear edge of the top of theheel-plates. Thus it will be seen that by means of the setscrews whichpass through the side plates and abut against the bushing the teeth arekept in perfect alinement, while the set-screws and bearingerollersallow the teeth to be adjusted to cut any depth in the ice and hold theteeth in a very rigid position.

I would state that balls may be used in the place of the rollers S andanswer the same purpose. t

'From this description, taken in connection with the drawings, it willbe seen that I provide a Very simple and durable securing means, yet avery eflici'ent, useful, and practical one; also,that it may be operatedreadily and easily, making it a very desirable,improvement.

l. An ice-marker, consisting of the frame, heel-plates carrying bushingsattached thereto and adjustably fitting in said frame, stopplatesadapted to fit in grooves between the frame above the heel-plates,insertible teeth adapted to pass through spaces between the stop-platesin front of the heel-plates, means for holding the heel-plates in theirproper adjustment, and means for adjusting the teeth.

2. In combination with an ice-n1arker having heel-plates adjustablysecured in. the frame thereof, of an insertible tooth adapted to beinserted in said frame in front of one of the heel-plates, and anadjusting means for said tooth consisting of the bearing-roller fittingin the space between the front of the tooth and the rear of thepreceding heel-plate, and a set-screw adapted to contact thebearing-roller to press thesame downward into engagement with the saidtooth and heelplate to hold the tooth in place.

3. In combination with an ice-marker 'nav-.

ing heel-plates with bushings secured to their sides, and means foralining said heel-plates consisting of the set-'screws passing throughthe sid es of the frame and contacting the bushings of the heel-platesto hold the plates in place in the frame and to aline the same, ofA

insertble teeth movably attached to said heel-plates to the forwardparts thereof provided with a means for adjustingthe cutting- -points ofthe teeth and to'hold the same in roller rigid to sustain the tooth inits desired adjustment.

5. In combination with an ice-marker, of heel-plates and insertibleteeth arranged in a space between the frame thereof, in such a manner asto leave a space or socket between the rear of a heel-plate and thefront of a tooth, a roller or movable bearing adapted to rest in saidsocket, and a set-screw adapted to be turned so as to press downwardupon said roller or bearing and hold the tooth tightly in place.

6. In combination with an ice-markerhavin g heel-plates with bushingssecured to their sides and set-screws entering the frame of the markerand adapted to abut against said bushings to aline the plates, of`stopplates adapted to fit in grooves between the frames above theheel-plates, insertible teeth adapted to pass through spaces between thetop plates in front of the heel-plates, a V- shaped socket, formedbetween the front of the teeth and rear of the plates, a roller or loosebearing resting in said sockets and a setscrew passing downward througheach of the said stop-plates directly above said sockets and adapted tobe turned and forced downward upon said roller or bearing to cause thesame to contact the front of the tooth and the rear of one of theheel-plates to hold the tooth iirlnly in place.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY BODENSTEIN.
